All patches are self contained and don't rely on others from
the set including 1/5 and can be taken separately. And some
changes go in separate patches to minimise conflicts. When
we agree on the approach, I'll send the rest converting some
other spots out of block.
Looks fine to me. Christoph, any concerns?
One note, though - s/fater/faster in patches 2..5 in the commit
message.
Noted. I expect there will be a bunch of conflicts, I'll resend
it, hopefully once you refined and posted some of your stuff.
